Why don't guitar amps have..... - Page 2

I think they stopped doing that because it was deemed dangerous.

From an electrical design point , there's NO reason you couldn't have a 110v/60Hz outlet on the amp. It could tap A/C BEFORE it goes to the amp. You would have to be careful as to how much current you'll be asking the cord to carry.

I noticed that the pedal snake produces 500ma which is plenty to drive the pedals. But I couldn't see anything but 9v outputs. Of course I could have missed it on that website.

Thanks for any insight.

My pedalboard has a few 9V pedals and one 12v pedal, and I run 2 separate Plines within the snake. I use a 3rd party power supply at the amp end to power the 12V. You can connect your power supply to the pedalsnake pigtail.

And I really miss the outlet on my DRRI.

That's the problem, you can never count on people to be careful with anything

Hi T-jack...

My amp sits on a stand 30"-35" off the floor, 3-5 feet behind me. Bringing a drop cord from there to a pedal rack etc would require a 15-20 extension cord from the back of the amp, to the floor, offset around my station, hopefully not under my feet - and I already have issues not wanting cables under my feet.

I much prefer to bring power from in front of me to power anything which is in front of me. So I don't see a plug-in on an amp advantageous.

I use a fan on stage and run my board through this

Pretty doggone easy problem to solve, especially if your amp has one of the new IEC power cables. Just get a Y-cable, chop off one of the Y ends, go to Home Depot and get a grounded female plug, put that on, and you're golden. It's very easy to set up a system so that you have just one cord running between your pedal board and amp in this fashion. Could not possibly take you 30 minutes plus a quick order online for a Y-cable.

A tube amp with 6V heater windings could power a bridge rectifier and filter to make an on-board DC supply. With 10V unregulated you could easily run it thru a 7809 regulator IC and have 9V rectified and filtered. As far as cabling goes, 18 gauge wire should run a dozen pedals or more without an appreciable drop from the rear of the stage to the front.

As someone replied, the AC supplied from the back of an amp somehow is not as strong and consistent as from a wall outlet... and I don't know why, but I do know that I played a gig once where outlets were at a premium, and so had to plug my amp into the back of the other guitarist's... after a short time, I started experiencing what many would call a "brown out"... my amp still worked and all, but it was very weak and fizzy sounding...

Seems to work just fine for the 9v adapter from my pedals though...

This is a bit surprising, because in these amps the accessory outlet is tapped straight from the incoming AC from the wall- not from the power supply of the amp. As long as the wall outlet can provide enough current to power all the devices, it shouldn't be a problem.

That said, it is also possible to introduce hum because of ground loops. I think that's the best reason not to use the accessory outlet for something like a pedal board.
